Ah yes. Gale. What IS the deal with him? Something even more special about him. Eh?

He is literally the only character in the game who is infected who you DON'T connect with. Everyone else, you have a Vulcan mind meld with as soon as you meet them. Not Gale. Oh no.

One thing to also keep in mind with shadow magic. It doesn't play by the rules. That's kinda the point of it. Shar created the Shadow Weave to be able to cast spells outside the rules Mystra established for the Weave.

So, I think - and again, we don't have a ton of real information, so who really knows - that although our souls are not free, our characters can still be resurrected as long as their tadpoles are alive.

The BG series has always been about the main character being "infected" by godhood. In BG3, I think the tadpoles in the mains are doing just that. They are turning the PC's into immortal gods. That's why Larian is perfect for the game. They've literally made 2 highly successful "I'm becoming a god" games.
